Brine Line Enhancement, Reach IV-D

Value: $1,155,284.96 Contractor: MMC Inc. Designer: RBF Consulting Schedule: May 2011 – May 2012

SAWPA received a $611,010 grant from the State Water Resources Control Board (Proposition 13) to fund two in-line sediment traps. The purpose of the sediment traps is to collect solid material before it reaches the Brine Line inverted siphons. The design and location of the sediment traps will greatly facilitate solids removal from the Brine Line and maintaining hydraulic capacity in the system. The concept of the sediment trap is to reduce flow velocities in the pipeline in a 10′ x 10′ x 16′ vault and allow heavier particles to drop to the bottom of the structure. Similarly, all lighter material, such as organic solids, will float to the top of the structure and allow for easy removal. Both the Schleisman and Euclid sediment traps.
